Description

Technical Field

[0001] The utility model belongs to the field of refrigeration equipment, in particular to a refrigerant flow dividing device for refrigeration and air conditioning. Background Art

[0002] Refrigeration air conditioning is a type of refrigeration equipment. Refrigerant is used in refrigeration equipment. Refrigerant is also called refrigeration working medium or refrigeration process. It refers to the working medium that realizes the refrigeration cycle in the refrigeration system. In the refrigeration equipment, the refrigerant entering the evaporator and condenser needs to be diverted to achieve uniform entry of the refrigerant into each capillary tube or evaporating coil so that the refrigerant can be fully dispersed. The refrigerant diverter device is a device specifically used for diverting refrigerants. The patent with authorization announcement number CN221349468U: "A Refrigerant Diverter Device" discloses a device that can divert refrigerants. However, when the device is in use, the gas phase components and liquid phase components in the refrigerant cannot be fully mixed in the diverter cylinder, which will affect the diversion quality of the diverter device.
